Question

Number of compounds/species from the following with non-zero dipole moment is ____

\(BeCl_2, \,BCl_3,\, NF_3, \,XeF_4,\, CCl_4,\, H_2O \,H_2S,\, HBr, \,CO_2, \,H_2, \,HCl\)

Answer 1

Correct answer is : 5

\(\underset {(\mu \ne 0)}{Polar \, molecule} : NF_3, H_2O , H_2S , HBr, HCl\)

\(\underset {(\mu = 0)}{Non \,Polar\, molecule} : BeCl _2 , BCl _3 , Xe F_4, CCl_4, CO _2 , H _2 \)
